We're not terribly fond of gadgets that change colors just for the sake of doing so--some Cravers are downright indignant, in fact--but this one may be an exception. If nothing else, Aigo's "Omnisphere" deserves at least some credit for its sheer number of colors: 4,096 of them in "high-illumination LED," according to Gadget Candy.

Like so much raver chic gear we've seen, this one has a brightness control that can be set to the beat and volume of the music. Not only that, but it will play the songs from an iPod as well with a built-in amp and storage for up to 250 tunes. It's perfect for an updated disco look too, because it looks like a lava lamp that's evolved into a 21st century look.
